I feel like this is not being properly acknowledged.
I am a huge fan of the Diaz's. I have watched all their fights and was watching them long before I'd even heard of Conor.
Now, to beat a Diaz, its well known that you do not stand in front of them, let alone move forward on them. They are typically beaten by being outwrestled or ocassionally outstruck via a game-plan using lots of kicking and movement (think Condit v Nick Diaz - although I actually thought Nick won that 48-47; or Nate v Josh T). Even in those instances, a Diaz has never resorted for extended periods of time to clinching against the cage and takedowns, let alone doing so to avoid striking at distance.
It was a very close fight but I do think Conor won. However, I have only watched it once and plan to re-watch...and who knows, I may re-assess.
But what is amazing and being overlooked is that Conor stood in front of and walked down Diaz, and so comprehensively outstruck him that Diaz (and the Diaz's always complain about this type of gameplan) resorted to clinch fighting and repeated takedown attempts.
Conor's striking/skills are sublime. His cardio is what's letting him down just a little bit, although he still fought hard for five rounds...well that and Diaz's iron chin and insane toughness.
